Eosinophilic mastitis mimicking a developing asymmetry.

Eosinophilic mastitis is a very rare form of mastitis with few reported cases in the literature. This is a case of eosinophilic mastitis in a 48-year-old woman which presented as a screen detected right breast developing asymmetry. No sonographic abnormalities were visualized on diagnostic workup, and subsequent tomosynthesis-guided biopsy was performed. Knowledge of this rare entity is helpful in the radiologic-pathologic correlation, diagnosis, and clinical management of future cases.

Local Recurrence of Invasive Secretory Breast Carcinoma in a Gravid Patient Post-Mastectomy.

This is a case of locally recurrent invasive secretory carcinoma of the breast during pregnancy, detected as a palpable mass in the reconstructed right breast of a 32-year-old female at 24 weeks gestation. The patient was initially diagnosed with secretory carcinoma 8 years prior, for which she underwent nipple sparing mastectomy followed by adjuvant chemotherapy and endocrine therapy. Due to pregnancy, the recurrence was treated initially with conservative excision alone, followed by definitive management postpartum which included wide local excision, sentinel lymph node biopsy and adjuvant chest wall radiation. Secretory carcinoma of the breast is a rare cancer with a predilection for young age and indolent course. This case report describes an unusual case of recurrent secretory carcinoma, of interest due to both its diagnosis during pregnancy, and its recurrence after nipple sparing mastectomy.
